Synthesis and analysis of single shaped reflector antennas

10 Jun 1986

Although geometrical optics (GO) is an asymptotic theory describ­ing electromagnetic fields of infinitely high frequencies only, it has for several years constituted the foundation for synthesis of reflector antennas. While dual reflectors are usually shaped to produce a certain aperture distribution leading to a pencil beam type pattern with high gain or low side lobes, etc., single reflectors may be synthesised to generate shaped beams by using the GO directly in the far field. In either of the cases, any design must necessarily be verified by a diffrac­tion analysis, because of the GO assumption made in the synthesis.
